well i've had to leave countless matches because of things i had to do right at that moment, and sometimes by accident, dont ask why it was an accident though,but u have a good point whoever leaves matches on purpose should be punished, maybe he or she should be banned from the game for a few days, or set there score back a hundred thousand, or maybe even put them to a rank so beyond our comprehension, that we have not seen yet, like i remember this one time mcbeth had his rank to like 212454524545, but anyway to top it all of people who leave matches on purpose alone should be severly(is that how u spell it? ???
) punished
